Optical resonant properties of plasmonic helix arrays fabricated by focused ion beam induced deposition have been experimentally investigated in scattering. The resonances have been studied under different polarizations of the incident light, demonstrating a significant polarization dependent behaviour of these nanostructures in the visible spectral range.
